I can't speak for them, but I believe he got tired of holding everyone's hand and spending countless hours making flat packs of various Marty's basically at-cost.
I met both just prior to that GTG to optimize Joe's subs for the GTG.
He had his HPF settings all messed up when I got there, they were set to 25hz (it's like a 15hz tuned ported).
I have to say though, that room had some of the smoothest bass I've measured to-date.
Once I disabled the DSP to measure the raw, I don't think there was even a 1db variance from 15hz to 200hz without eq, due to the small width of that room which made the subs fit in an ideal quarter-wave placement.
All I ended up doing was applying a 6db/oct 20hz HPF, which got him flat to 14hz for the GTG.
His inukes weren't saving settings anymore and producing massive hiss in his room, so he ended up replacing them with speakerpower soon after, last I heard...
Joe picked my brain for like an hour about REW. That and debugging his inuke settings basically took up all my visit-time. I only spent like 5 minutes listening to his system. Pretty much the opposite of what I had initially planned, but it is what it is. I didn't even get to hear Donny's UMC-2/Oppo103D that he had brought over...
The only thing I learned was that the JTR mid is better sounding than the Fusion-12 mid. The entry-level JTR tweeter is best designed for narrow/deep rooms because IMO it's like listening to a laser beam, where as the SEOS-12 or 15 is more like listening to a cone of sound, and traditional HiFi speakers like B&W 800's are like listening to a wall of sound. Apples vs Oranges really. The differences were immediately obvious to me.
I find that once you get 10db over THX the SEOS's tend to bite your head off, they start to resonate in the 10-20khz region, that and, like most horned tweeters they start rolling off above 6khz. That's why I added a Fostex super to each of my fronts to flatten the response to ultra-sonics and reduce the resonances at higher SPL, as a result I can play my system a good 6db louder before any hint of ear fatigue or driver strain. Something you don't get with the flat-pack OOTBE. With stock XO's and at lower SPL's/watts, one would not notice these things nearly as much, especially an untrained/normal listener.
I've spent the last 10 years perfecting the active crossovers in my HT (mids and tweets in particular), trying to extract every last detail from the drivers in play. I use my HD800 headphones with balanced-power as a reference/guide, as well as my prior years owning B&W 803's.
n-th way speakers and DSP fine-tuning can make a WORLD of difference...
Mine sound nothing like the stock-experience.
My room also has a heavy amount of acoustical treatments. About 40% wall coverage to a depth of 1-12inches, with the averaging being around 3.5inches. This was required to keep my room from sounding like an echo chamber when uploading youtube vids.
The key with acoustical treatments is to apply enough of them to kill the echo, but not so many of them to kill the life of the sound system. It's a delicate balance.
Throughout most of the day, and especially at night, my room has an average noisefloor of about -5dbA to -15dbA. (With the amplifiers and electronics off that-is.)
Unfortunately all my FP clones are stock fans and I haven't enclosed my rack-room yet either, so it literally sounds like a blower-assisted SpaceX liftoff in there (I'd say ~45dbA at ~6ft); but once the watts come out you can't even hear yourself think, so it's all-good...
